SEPARABLE FASTENER.

Specification of Letters Patent.

Application filed April 19, 1915. Serial No.

To all whom it may concern Be it known that I, PAUL Hunowroz, a subject of the Emperor of Germany, and a resident of New York, in the county of New 5 York and State of New York, have invented certain new and useful Improvements in,

Separable Fasteners,

is a specification.

his invention relates to improvements in snap fasteners and in particular to the of which the following type used in engaging one portion of a shoe top with another.

The object of the invention is to provide a simple, yet highly efficient, securing means applicable broadly for many purposes and specially appropriate for use in connection with shoes in place of the hitherto common lacings or buttons.

It is a further fastenings in forms rigidly attachable along the edges to be closed,

disengaged with even greater despatch, when it is so desired.

These and other allied objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming part of this specification, and in which 2- Figure 1 is a perspective view of the up per part of a shoe, shown in an open position and indicating the application of the invention.

Fig. 2 is a fragmental sectional View, taken substantially on line 3-3 of Fig. 1.

Fig. 3 is a like'sectional view, taken on line H of Fig. 1.

Fig. 4 is an enlarged perspective view of one of the fastener members, and,

Fig. 5 is a similar view of the other fastener member.

The essential elements of the invention are shown in detail in Figs. 5 and 6, the latter of which discloses a stiff, yet resilient, wire formed with end loops or eyes 10 and 11 respectively extended in opposite" directions, by means of arms 12 and 13, fromperpendicular side members 14 and 15, bent at right angles to the arms and joined by a reentrantly formed, open spring loop 16, the opening of which is of lesser magnitude than the loop itself.

This element is secured in such manner 5 that the sides 14 and 15, together with the object to provide such the fixed element, these Patented Feb. 20, 1917. 22,311.

loop 16, extend above the surface, (see Figs. 2 and 5) the loops l0 and 11 being rigidly engaged with the article by means of tubular rivets 17 and 18, the latter of which may be engaged below the outer covering and therefore obscured by it.

The other fastener element is also formed with loops or eyes 20 and 21, from which 'n the same plane, arms 22 and 23,

manner that the the outer or face surface of the top.

By reason of the distance between the seand manner of fastening them breaking point, and further, that the disposition of material in the first described element is such as to afford a desirable lethe direction of the arms 12 and 13.

It is to be observed that the opening to the loop 16 is slightly less than the distance between the points 24 and 25, so that when the movable element is firmly pressed upon points will enter and become engaged in the loop 16, both elements being sufliciently resilient to permit of this, forming a snap fastening of unusual merit.

It is also to be noted that the proportion of i t e parts are such that while in engagement they are substantially rigid and can not be separated by a pull exerted in the direction of-the length of the loop 26, yet by raising the movable part of the article, the parts can be readily separated.

To accomplish this purpose an elastic gore 30 is secured at its sides and bottom to an inelastic border one side 31 of which is firmly engaged with the edge of the shoe top in such manner that the gore 30 acts as a cover strip over the front of the shoe, while the other side 32 of the border is unattached, acting as a flap, to the edge of which is engaged the snap elements shown in Fig. 5.

Having thus described my invention, to-.

said arms, upwardly and inwardly to provide a reentrant spring loop, said loop being disposed at right angles to the arms of the attaching eyes, and a hook member formed from a single strand of wire and bent to provide spaced attaching eyes, arms extending from said eyes and bent inwardly to form a neck portion and then outwardly to provide an elongated spring loop in line with the said arms, the neck portion being adapted to yieldingly engage within the said rentrant spring loop for the purpose set forth.

Signed at New York, in the county of New York and State of New York this seventh day of April, A. D. 1915.
